Patent JP-H06331347-A (JP)
Title: Reflection type photoelectric sensor
Inventor: TANAKA TAKASHI
IPC: G01C3/06
Filed: 1993-05-18
Abstract: PURPOSE:To simply eliminate the problem due to saturation when the quantity of reception light is large. CONSTITUTION:In the title sensor which is provided with a light projecting member and a light reception part for receiving reflected light of the light from the light projection member by a target and obtains distance information to the target by the light reception position of reflected light at a light reception part, a light screening part 40 is provided at the center of a light reception part 4 for outputting the reception light signal from both edges. Since a center part where the light from the target at a near distance falls is blocked, the quantity of reception light from the target at a near distance can be suppressed. The center part does not interfere with distance detection, thus preventing a range-finding function from causing any new problems.

Patent JP-H01286524-A (JP)
Title: Pll protection circuit
Inventor: IKEMOTO NAOTOMO
IPC: H03L7/08
Filed: 1988-05-11
Abstract: PURPOSE:To prevent malfunction of the circuit by detecting the malfunction of a phase locked loop(PLL) and holding an applied voltage to a VCO. CONSTITUTION:A pulse given only at a slope of a trapezoidal wave is given to a D input of a D flip-flop 12. When the PLL is locked, since a sample pulse exists at the slope of the trapezoidal wave, an output of the D-FF 12 goes to a low level. If the PLL is unlocked or the sample pulse comes to an abnormal location, the output of the D-FF 12 changes from a low to a high level to hold the applied voltage of the VCO 6 for a prescribed time through a monostable multivibrator circuit 10. Thus, the abnormal operation of the PLL circuit is prevented in advance.

Filed: 1979-09-12
Abstract: PURPOSE: To effectively recover combustible gas and at the same time to recover metals, by contacting with steam, noncombustible solids such as carbon black, produced in a pyrolytic furnace.  
     CONSTITUTION: Waste rubber 7 reinforced with metals and carbon black is introduced through charging doors 6 into a pyrolytic furnace, and allowed to fall through a predrying zone 1 into a pyrolytic zone 2, where the waste rubber is thermally decomposed at 300W1,000°C to produce dry distillation gas and noncombustible solids consisting of carbon black and metals. Then, the noncombustible solids are allowed to fall into a zone 3 for forming water gas and reducing gas, where the carbon black is contracted with steam or water injected from an injection nozzle 9 to generate water gas. On the other hand, the unreacted residual carbon falls into a combustion zone 4, where the carbon reacts with heated air prepared by heating to 1,600°C or higher, air introduced from a nozzle 10 by a burner 11, to generate reducing gas and at the same time to melt the metals in the solids, which then accumulate at the furnace bottom 5. The dry distillation gas is recovered from a recovery conduit 8.

Abstract: PURPOSE:To highly accurately detect the toner density in a developing agent by detecting the fluidity of the developing agent falling down from a container with the use of detecting measn. CONSTITUTION:Normally, a first shutter plate 23 covers the head of a hopper 13, and a second shutter plate 24 is retracted from an outlet 14. When in the toner density detecting operation, the first shutter plate 23 is shifted to a position shown in broken lines, and the second shutter plate 24 is shifted to shut off the outlet 14. When the developing agent is stored in the hopper 13 after a preset time lapse, the first and second shutter plates 23 and 24 are returned to their initial positions, and the developing agent in the hopper 13 simultaneously begins falling from the outlet 14 into a cylinder 15.
